In a large bowl, mix together the flour, oats, baking powder, soda and salt. In a medium bowl, whisk together the yogurt, honey, oil, eggs and vanilla.
Pour the wet ingredients into the dry ingredients and mix together until just combined. Fold in the blueberries.
Line a 12 count muffin tin. Divide the dough evenly into 12 muffins- they should fill the liners right to the top and may even be slightly heaping.
Optional: Sprinkle a pinch of turbinado sugar onto the top of each muffin.
Bake at 375 °F for 18-25 minutes until a toothpick inserted into the centre has just a few moist crumbs and the muffins bounce back from a light touch.
Remove muffins to a wire rack to cool completely.
